BURNING CHAMBER. FUR. INCINERATORS.

Applicatiiin filed August 1, 1924, Seria1 No. 729,652.

ing at Dallas, in the county of Dallas and State otTexas, have inventedcertain new and useful Improvements in Burning Chain bers forIncinerators, of which the following is a specification.

. This invention relates to new. and. useful improvements in burningchambers for incinerators.

Theobject ofthe invention is to provide means in a burning chamber forsuspending large and slow burning matter in the chamber above the firegrates, whereby said matter is dried out and burned by fires both aboveand below it and. cremated in. a highly efficient and improved manner.

A further object is to providesuch suspension means between battlewalls, whereby a greater circulation and more intense incineration maybe carried out.

Another object isto provide such suspension. means in combination with.pre-drying and. liquid collecting means in thechamber, so that matterdelivered to the suspension grates will be more orless free 'fromliquidsand. the latter ,prevented to a. large extent, from passing to the tiregrates and. ash pits.

A still further object is to provide suspension grates composed of waterconductors, whereby said grates are prevented from burning. out andwhereby hot water and steam maybe obtainedfor various purposes.

Another object is to provide a burning chamber having a battle Walltherein with a flame passage therethrough and suspension grates on eachside of. said wall, whereby the flames pass through said-passage aboveand below the. grates. y

A further objectis to provide doors whereby access through the front.wall of the chamber may behad-to the nppersurface of the suspensiongrates as well as to the fire grates below, so that both may beefliciently stoked and non-combustible matter easily removed fromeither.

. A; construction designed. to carry out the invention will. behereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawings,in which anexampleot the. inventio-nis shown, and wherein:

Fig. 5 is an enlarged transverse. vertical sectional view. on the'line5..-5 ofFig. 1,

Fig. 6is a cross.sectional view taken on the line 66.of Fig. 5, and- 7Fig.7 is a detailof one of the roof blocks...

In the drawings the numeral. 10 designates. a base upon which a frontwallall, an end. wall 12,a rear wall 13wand anend. 14 are erected: Thesewalls and the base. are suite ably constructed in accordancewithincinerator engineering. The rectangular struc tureformed by thesepartsis comparatively shallow from front to rear in. proportion -to itslengthbetween the end walls. This is an important featureas it permits allparts of the interior to be reached through open? ings in the frontwall, with. a short handle rake and thus cuts down thestoking roomusually required in frontnof the incinerator.

A floor .15 is supported at the upper-ends of the wall and is composedof -a concrete mixture reinforced by I-beams 16 extending .at right.angles to each, other and having their ends supported inthe walls. Theincinerator is charged from the floou. A ver tical division wall 17adjacent thewall 14 divides the interior of the incinerator, the greaterportion, about fountifths more or less, lyingto the right (Figs Band 4)and constituting a main or burning chamber. I provide.- a floating or.detached roof or arch for, this chamber composed of tire resistingblocks or tile18, suspended from clamps 19 (Fig. 7) supported by eyebolts 2Q depe-nd- -g fnolnhanser 2. clampe t the ams 16. These blocksmay assume a desired o m and i efit ina e he re no t ed to the walls 1of the furnace,- thus, allowing r xp nsi rand e t ac on n P r-mi tingready removal and. replacing.

Over the rear portion of the chambenthe roof is horizont l. ut iinclined down- -wardly over the front portion thereof. By

using square blocks uniformity is had, and rectangular charging hoppers22 may be used. The hoppers have their upper ends flanged andcountersunk in the floor 15. Each hopper has a vertical collar 23secured to its lower end and surrounded by the blocks 18 of the roof.The details of the hopper form the subject matter of a ctr pendingapplication filed August 1, 1924:, Ser. No. 729,650. In each collar ishinged a cover composed of a tire resisting tile 24 secured in a back25. interior flange 26 at the bottom of the col lar. From. the front endof each cover a flexible connection 26 extends upward and passes behinda pulley 27 on the rear wall of the building. By this means the covermay be swung upward in a convenient manner.

The hoppers have their greatest length directed forwardly as is shown inFig. 2 and are located near the rear wall 13. Within the burning chamberand under the hoppers is an evaporating and drying table 28 inclineddownwardly from the rear wall and having its front end supportedabovethe base 10 on a vertical wall 29. The table is suitably formed oftire resisting material and may be made in sections or block so as to bereplaced. This elevated table has a longitudinal sump or trough 30 alongits front edge for catching and retaining the liquids, whereby thelatter areevaporated and prevented from flowing down intothe ash pits.This table is arched over a fine or tunnel 32 extending parallel to therear wall 13 and behind the wall 29. The bottom of the tunnel is formedby'the base 10. As will be hereinafter explained the hot gases and aircurrents escaping from the burning chamber pass through said tunnel,thus heating the table from the underside.

The table 28 and tunnel 32 constitute dry-- ing or pro-heating means andare specifically covered in my oo-pending application filed August 1,1924, Ser. No. 729,653. As will be obvious from the followingdescription, it will be seen that any type of table or equivalent meansheated in any suitable manner could be used.

The burning chamber is divided by transverse vertical battle walls 33extending from the base 10 to the roof andfrom the front wall 11 tothewall 29, and the front edge of the table. Between the walls 33 and oneach side thereof. are fire grates 34 of any suitable type. These gratesare supported by the walls 11, 12, 17, 29 and33above the base 10 andabout midway the height of the front ofthe table 28. Ash'pits 35 areformed below the lire grates and access is had thereto through doors 36in the front wall 11.

Above the grates 3a are suspension grates The tile rests upon an drawnoff by opening the valve.

37 located in a plane substantially flush to the front edge of thetable, but subject to variation. .1 have shown three units (Fig. 3)separated by the baflie walls 33. Each unit s composed of a front header38 and a rear header 39 parallel to the front wall. 11 and the table 28,respectively the heads are connected by spaced tubes 40 forming thegrate bars. A water supply pipe ll eX- tends into the wall 12 and isconnected to the adjacent rear header 39. The front header of the firstgrate is connected to the front header 38 of the second grateby acoupling 42, while the rear header 39 of the second grate is connectedto the rear header of the third grate by a coupling 43. A discharge pipe44 leads from the end of the header 38 of the third grate adjacent thewall 17. It will be apparent that water entering the first grate (Fig.3) at the right will flow through the various units and es:

cape through the pipe 44 either as hot wa ter or steam. I

The pipe 44 is connected with a vertical pipe 45 which enters a manifold46 disposed alongthe base 10. The right hand end.

(Figs. 3 and 6) of the' manifold is closed by a cap 4-7, while a valve48 is connected to the other end and has a nipple 49. Risers 50 extendfrom the manifold and are connected to nozzles 51 extending through thefront wall 11 into the ash pits 35 below the grates 34. Steam may thusbe supplied in jets from the nozzles. Hot water may be Doors 52 in thefront walls give access to the spaces between the grates; while otherdoors 53 give access to the grates 37. Flared liners 54. in the wall 11at each of these doors make for free stoking and access to any part ofthe burning chamber. 7

Each battle wall has a'central opening-55 extending from a point betweenthe grates 31 and 37 to the roof of the burning cham her. A similar butlarger opening 56 is provided in the wall 17 forthe escape of theproducts. It will be seen that the air currents and flames will passthrough the openings 55 in the battle walls above the grates 3el'andabove and below the grates 37, thus thoroughly igniting and burningmatter deposited upon said grates. The flames and currents will alsowhip around the rear ends of the baflie walls and pass over the front ofthe table 28. These flames, currents and cases will be drawn toward theopening 56 and at this point the fire will be most intense, providing acut-off fire through which all products must pass.

.The essential feature of the invention being the suspension grates andthe baffle walls, it will be seen that the garbage and trash might bedelivered directly to said grates. The openings in the walls permit afre passage and circulation of the flames and allow them to pass aboveand below the matter suspended on said grates. The shallow burningchamber and the flared openings permit the grates to be efficientlystoked and also afford a ready means of removing tin cans and othernon-combustible matter.

So far as this invention is concerned the outlet 56 may connect with apassage for conducting the products to a smoke stack. In the drawings Ihave shown a superheating chamber 57 and a combustion chamber 58 formedbetween the division wall 17 and the end wall I l. The chamber 57 isconnected with the opening 56, while the chamber 58 is connected withthe tunnel A grille 59 is placed at the entrance to the tunnel.

The products passing through the tunnel heat the table Ducts 60 leadfrom the discharge end of the tunnel and are con nected with a smokestack (31. The stack creates a draft so that the products are drawnthrough the openings in the baffle walls and the opening 56, wherebycombustion is promoted in the burning chamber.

Various changes in the size and shape of the different parts, as well asmodifications and alterations may be made within the scope of theappended claims.

What I claim, is:

1. In an incinerator, the combination of a burning chamber having acharging hole in its roof and an outlet at one side, a baflie wall inthe chamber having an opening therethrough, fire grates extending oneach side of the wall, the opening of the wall. extending above saidfire grates, and suspension grates on each side of the wall, the openingof the wall extending above and below the suspension grates.

2. In an incinerator. the combination of a burning chamber having acharging hole in its roof, an inclined drying table in the chamber underthe charging hole, a battle wall at right angles to the table,suspension grates on each side of the bafile wall con-- tiguous to thetable, and fire grates on each side of the battle wall spaced below thesuspension grates in front of the table.

In an incinerator, the combination of a burning chamber having acharging hole in its roof, an inclined drying table in the chamber underthe charging hole, a bafile wall at right angles to the table,suspension grates on each side of the battle wall contiguous to thetable, and tire grates on each side of the bailie wall spaced below thesuspension grates in front of the table, the batlie wall having anopening extending above and below the suspension grates.

t. In an incinerator, the combination of a burning chamber, an inclineddrying table at the rear of the chamber, baiiie walls extending from thefront wall of the chamber to the table, suspension grates between and oneach side of said baffle walls contiguous to the table, fire gratesunder the suspension grates, the battle walls having vertical openingsextending above and below the suspension grates, and doors in the frontwall giving access to the surfaces of the suspension and fire grates.

In an incinerator, the combination of a burning ehan'iber, a dryingtable extending along the rear wall of the chamber, the chamber having acharging hole over the table, vertical balile walls spaced from thesides of the chamber and also spaced from each other and extending fromthe table to front wall of the chamber, the battle walls havingconnnunicating openings therein, fire grates in the chan'iber separatedby the baflle walls and below the front edge of the table, andsuspension grates overthe fire grates and contiguous to the table andthe openings in the battle walls, the space above the table beingunobstructed whereby the hot gases may pass around the rear ends of thebattle walls and over the table.

In testimony whereof I affix my signatin'e.
